Title: Pressure swing adsorption using mixed adsorbent layer
Inventor: ACKLEY MARK WILLIAM
IPC: B01D53/04
Filed: 2001-09-14
Abstract: PURPOSE: A method and apparatus for employing a mixed transition adsorbent layer in pressure swing adsorption(PSA) and vacuum pressure swing adsorption(VPSA) adsorbent bed systems having two or more layers of adsorbent materials are provided. CONSTITUTION: Figure 4A shows a bed configuration employing a mixed transition region that exploits the temperature conditions present in the bed. The process performance is improved by selecting and layering adsorbents on each side of a mixed transition region according to the adsorption properties of the individual adsorbents and their mixtures and tailored to the local temperature conditions in the bed. Surprisingly, this improved performance is achieved with adsorbent configuration boundaries (aa/ab and ab/bb) that do not necessarily coincide with the separation boundaries (A/B and B/C). Through the combination of distinct layered adsorbent regions with the mixed transition region between the two, the adiabatic separation factor is maximized at each temperature along the bed length. The bed is configured with NaX in region (aa). The adsorbent in region aa is operating in the prepurification zone (zone A) of the adsorbent with a rapidly falling temperature profile. This region comprises about 5-10% of the total adsorbent. Region bb contains LiX and occupies all of zone C and part of zone B of the adsorbent. This region contains about 70-80% of the total adsorbent. A mixed transition region (ab) is inserted between the layers of the individual LiX and NaX adsorbents. The lower end of this region is 100% NaX at the boundary aa/ab, and the composition of this region gradually increases in LiX until 100% LiX is reached at the boundary ab/bb. The length of region ab (also called the depth of ab) is tailored to achieve the maximum performance in the continuously varying low temperature region near the entrance of the main separation zone (zone B). The required size of the transition region (ab) depends upon the process conditions and the adsorbents. The size of the transition region is thus established upon the basis of the thermal state of the adsorbent in the bed and upon the separation characteristics of the adsorbent mixture.
